Answer 1

il n'y avait aucune référence de date devrait de

été émis

Answer 2

Regardez la dernière ligne:

Dans

/var/www/mywesbite/src/mywebsite/../mywesbite/shop/models.py 

dans la méthode __unicode__ vous avez une ligne:

return ", ".join((str(self.account),self.date.strftime("%b. %d, %Y, %H:%M %p"))) 

et que self ne savent pas sur l'attribut date. Peut-être qu'il n'y en a pas défini. Si vous n'êtes pas sûr, changez cette déclaration de retour particulière pour retourner quelque chose de dénué de sens mais correct pour le moment et voir, si c'était la seule erreur.

Answer 3

La pièce importante est dans les dernières lignes (rappelez-vous que le dernier appel, à savoir: celui qui provoque l'erreur, est toujours imprimé dernier dans un stacktrace):

File "/var/www/mywesbite/src/mywebsite/../mywesbite/shop/models.py", line 1105, in  
    __unicode__ 
    return ", ".join((str(self.account),self.date.strftime("%b. %d, %Y, %H:%M %p"))) 
    AttributeError: 'PasswordResetRequest' object has no attribute 'date' 

Ce que cela signifie est cela, dans le fichier mywebsite/shop/models.py sur la ligne 1105 (qui est dans votre méthode def __unicode__(self):), vous appelez self.date.strftime(), mais le modèle n'a aucune propriété appelée date.

Answer 4

Eh bien, le problème est dans la méthode unicode du modèle PasswordResetRequest défini dans shop/models.py. Vous essayez d'accéder à self.date sur cet objet et il n'a pas d'attribut de date.

Peut-être que si vous collez votre modèle que je pourrais aider plus ...
